Here is the thing about OU, thankfully probably their best offensive player is going to the NFL in Stevenson. Dude was suspended for the first half of the year, and they were a different team when he came back. They do have some really good young RB's though so they will reload there.
Mimms and Rambo will be a big problem for Nebraska and like they said last night in the game once they find a spot for Mikey Henderson, he will be a matchup nightmare.
They are smallish on the D Line, but their backers are big and can move. A person will know more about NU after the first two game, but gonna have to have a power and QB run game to keep it close.
